Which portals use a 3MB file size limit?
A 3MB limit is found most commonly on insurance claim submission portals, bank account opening and KYC update forms, and loan application portals. Major Indian insurance portals including LIC, HDFC Life and SBI Life impose a 3MB limit on claim documents. Bank account opening portals (HDFC, ICICI, Axis, Kotak) typically accept KYC documents up to 2–5MB. Home loan and personal loan application portals on bank websites frequently cap supporting documents at 3MB each.

Compressing specific document types for banking and insurance
Bank statements in PDF format are typically generated digitally and compress by only 10–20% because they contain minimal image data. Scanned physical bank statements compress very effectively — a 15MB scanned 12-month statement typically reduces to under 1MB. Insurance policy documents are usually digital PDFs and compress by 20–40%. Scanned claim supporting documents (hospital bills, invoices) compress by 70–90%.
